    SAFETY PRECAUTIONS (Always read these instructions before using this equipment.) Before using the product, please read this manual, the relevant manuals introduced in this manual, standard PLC manuals, and the safety standards carefully and pay full attention to safety to handle the product correctly.
  • Page 4 [Design Precautions] WARNING When a safety PLC detects an error in an external power supply or a failure in PLC main module, it turns off all the outputs. Create an external circuit to securely stop the power of hazard by turning off the outputs.Incorrect configuration may result in an accident.
  • Page 5 [Installation Precautions] CAUTION Use a safety PLC in the environment that meets the general specifications described in the QSCPU User's Manual (Hardware Design, Maintenance and Inspection).Using this PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product While pressing the installation lever located at the bottom of module, insert the module fixing tab into the fixing hole in the base unit until it stops.
  • Page 6 [Wiring Precautions] CAUTION Tighten a terminal block mounting screw, terminal screw, and module mounting screw within the specified torque range. If the terminal block mounting screw or terminal screw is too loose, it may cause a short circuit, fire, or malfunctions. If too tight, it may damage the screw and/or the module, resulting in a drop of the screw or module, a short circuit or malfunctions.
  • Page 7 [Startup and Maintenance precautions] WARNING Do not touch the terminals while power is on.Doing so could cause shock or erroneous operation. Turn off all phases of the external supply power used in the system when cleaning the module or retightening the terminal block mounting screws, terminal screws, or module mounting screws. Not doing so could result in electric shock.
